Hi,
thanks for the reply.
Linux server (enp0s8)(bond0) ======== (po1)(xe1) switch
Linux server (enp0s9)(bond0) ======== (po2)(xe2) switch

I am even attaching the tcpdump log on back to back connected links
below as the lacpdu generated from linux server has collecting
distributing bit set as TRUE.
